Version 0.1.4

##Breaking API Changes*

  • Collection methods
    • Return result via callback see below docs for examples
  • See TODO
  • Pull requests are always welcome
  • MongoDB style queries
  • Persistence for Collections
  • Data Persistence Plug-in system
  • Finish Docs
  • Add more datastores
  • Add remaining functions
  • Code/function Clean up and optimization
$ git clone https://github.com/euforic/monglodb.git
$ cd monglodb
$ npm install -d
$ make clean && make

Builds will be located in dist folder

var Monglo = require('monglo').Monglo;
var db = Monglo('DBNAME');

Datastores for persistence your db with local/remote data

var monglo = require('./index').Monglo;
var db = monglo('DemoDB');
 
//Define a store locally or import a common js module;
//See source for all available functions
function DemoStore(){
  return {
    insert : function(args){  },
    update : function(args){  },
    open   : function(args){  },
    remove : function(args){  },
       all : function(args){  }
  };
}
//Load the store in Monglo
db.use('store', new DemoStore());

Find all docs that match query parameters

db.someCollection.find({}, function ( errorcursor ){ });

Find a single doc that matches query parameters

db.someCollection.findOne({}, function ( errordoc ){ });

Insert a new doc

db.someCollection.insert({text: "Hello, world!"}, function ( errordoc ){ });

Update and existing doc

db.someCollection.update({name:'tester'}, {$set: {text: 'test'}}, function ( errdoc ){ });

Update doc if exists if not insert the new doc

db.someCollection.save({DOC}, function ( errdoc ){ });

Remove the doc matching the query selector

db.someCollection.remove({uid:'34245'}, function (err) { });

Saves snapshot of collection's current state in memory Backup ID defaults to a new ObjectID string if non is provided

db.someCollection.backup('backuId_1234', function (err) { });

Restore the state of a collection from backup

db.someCollection.restore('backuId_1234', function (err) { });

Lists available Backups

db.someCollection.backups(function (err) { });

Remove a backup from memory. If backup id is left empty all backups will be removed;

db.someCollection.removeBackup('backuId_1234', function (err) { });

To create a cursor, use find. To access the documents in a cursor, use forEach, map, or fetch.

db.someCollection.find({}, function (errcursor) {
  // Cursor instance for query 
});

Call the callback function once for each matching document.

someCursor.forEach(function(doc){ console.log(doc); });

Map callback over all matching documents. Returns an Array.

someCursor.map(function(doc){
  doc.fullname = doc.firstname+' '+doc.lastname;
  return doc;
});

Return all matching documents as an Array.

someCursor.fetch(function(docs){ console.log(docs); });

Returns the number of documents that match a query.

someCursor.count();

Resets the query cursor.

someCursor.rewind();

Watch a query. Receive callbacks as the result set changes.

Monglo.Collection('my_collection');
var someCollection = db.someCollection('mycollection');
 
//See docs for all events 
someCollection.on('insert', function(){ /** Do something  **/ });
someCollection.on('update', function(){ /** Do something  **/ });
someCollection.on('remove', function(){ /** Do something  **/ });
someCollection.on('find', function(){ /** Do something  **/ });
someCollection.on('createCollection', function(){ /** Do something  **/ });
someCollection.on('removeCollection', function(){ /** Do something  **/ });
